Title: Adjustable bracket for building construction
Inventor: SPRONKEN JOHN R
IPC: E04B2/94
Filed: 1991-10-08
Abstract: Abstract An adjustable support bracket assembly is described for supporting a building wall panel or other heavy article on a vertical support structure, e.g. a column.  The assembly includes a pivot pin which is fixed to the vertical support structure, e.g. welded to an inner edge face of a column with a portion of the pin projecting laterally beyond an edge of the column. A substantially horizontal support member is pivotally supported at the inner end thereof on the pivot pin and has a load bearing portion extending outwardly beyond the outer edge of the vertical support structure.  This horizontal support member also includes a pivot arm portion projecting upwardly or downwardly from the horizontal portion and having a threaded hole in the pivot arm portion remote from the horizontal portion.  A threaded bolt is mounted in the threaded hole of the pivot arm and this bolt is adapted to engage the vertical support structure, e.g. column, such that rotation of the bolt results in upward or downward movement of the load bearing portion.

Patent CA-2061435-A1 (CA)
Inventor: BENNETT JINAN G
IPC: D21F1/00
Filed: 1992-02-18
Abstract: A seam for a papermakers wet press felt having a flat woven base  fabric with the crimped yarns oriented in a lengthwise or machine direction is disclosed.   Orientation of the crimp in the machine direction lends itself to an analysis of the crimps per square inch based upon the crimp length and warp end count.  Utilizing the crimps per square inch figure, it is possible to establish the approximate minimum length of the join in the machine direction.   The minimum machine direction length,  in inches,  of the join area is approximated by the equation:  approximate joined length equals 500 divided by the crimps per square inch in the repeat pattern of the woven base fabric.

Abstract: A speech signal coding apparatus inputs a pitch period generated by coding a speech signal, and outputs information on a range for said pitch period, together with the pitch period. A speech signal decoding apparatus inputs the pitch period and the above information on the range, and determines whether or not the pitch period is within the range. When the pitch period is determined to be within the range, the speech signal decoding apparatus outputs the above pitch period. When the pitch period is determined not to be within the range, the speech signal decoding apparatus outputs as a pitch period a predetermined value within the range.
Patent CA-2066952-A1 (CA)
Inventor: ISO KEN-ICHI
IPC: G06F15/18
Filed: 1992-04-23
Abstract: A speech recognition method according to the present invention uses distances calculated through a variance weighting process using covariance matrixes as the local distances (prediction residuals) between the feature vectors of input syllables/sound elements and predicted vectors formed by different statuses of reference neural prediction models (NPM's) using finite status transition networks.  The category to minimize the accumulated value of these local distances along the status transitions of all the prediction models is figured out by dynamic programming, and used as the recognition output.  Learning of the reference predic-tion models used in this recognition method is accomplished by repeating said distance calculating process and the pro-cess to correct the parameters of the different statuses and the covariance matrixes of said prediction models in the direction of reducing the distance between the learning patterns whose category is known and the prediction models of the same category as this known category, and what have satisfied prescribed conditions of convergence through these calculating and correcting processes are determined as re-ference pattern models.

Abstract: A robust tone detector is realized by applying a single taper, which provides a relatively narrow bandwidth filter, to a received signal and, then, performing a Discrete Fourier Transform of the tapered signal. The result of theFourier transform is used to obtain an estimate of energy in the frequency domain of the expected tone. A prescribed selection algorithm based on the relationship of the received signal energy in the time domain and the energy estimate in the frequency domain is used to determine whether a valid tone has been received. Robustness of the tone detector is improved by performing a plurality of Discrete Fourier Transforms of the single tapered version of the received signal at a corresponding plurality of frequencies relative to the nominal frequency of an expected one or more tones. A further improvement in the tone detector is obtained by dynamically adjusting tone acceptance thresholds based on a measure of channel impairments.
